OIL-BURNER.

Specification of Letters Patent.

Patented June 21, 1921.

Application iiled September 20, 1920. Serial No. 411,436,

To f/ZZ' 107mm it may concern.'

Be it known that l, JOHN Rrionns, a citizen of the United States, residing at Seattle, in the county of King and State of lWashington, have invented a certain new and uselful .improvement in Oil-Burners, of which the l'ollowing is a specilication.

lli/ly invention relates to improvements in oil biu'ners or the type that are adapted to burn hydro-carbon oils, as kerosene, and the object o'l" my invention is to provide a burner einliiodying novel means of pre-heating the fuel oil prior to the latter entering the burner conduit.

Another object is to provide an oil burner embodying means to deflect the intense heat away from the burner conduit, thus preventing` the same 'from becoming overheated and carbonized, while still furnishing sutlicient heat radiation to sustain and maintain adequate gasilication oiI the fuel within the said conduit until it reaches the combustion aperture.

A 'Further object is to provide oil burner wlu'eh is inexpensive and simple in its plan of construction, ellicient and reliable in its operation, and which is easily cleaned and will not readily get out of order.

lilith the above and other objects in view which will appear as the description proceeds the invention consists oi' the novel construction, adaptation, arrangement and combination ota parts hereinafter described and claimed.

l accomplish these objects by devices .illustrated in the acconipanying` drawings, whereinc Figure l is a, top planview of an oil burner embodying the features of my invention.

Fig. 2 is a view in medial vertical section ot the saine.

Referring to the drawings, vthrough which like reference numerals designate like parts, the numeral 10 designates a fuel supply pipe communicating with a 'fuel vaporizing chamber il. Said chamber is preferably formed substantially as illustrated in the drawings and is provided with an integral concave top wall 12. A plug 13 is threadably secured through the side wall of said chamber and serves the double purpose as a supporting means for said burner and as a means or closing a cleanout part 14 prov1ded in said wall.

A burner conduit l5 is threadably secured through the side wall otl said chamber diametrically opposite the said plug 13 and in conjunction therewith serves as a supportingineans for the burner. The said burner conduit is preferably formed of a single piece of pipe and comprises an outwardly extending portion l5, an upwardly eXtending portion lo, a diametrically horizontal portion 17, and a downwardly disposed por" tion 18, all of which portions are substantially in the same central vertical plane. The end of the said burner conduit is provided with a cap 19. A combustion aperture 2O is provided in the under side of the horizontal portion 17 ot the said burner conduit, vertically above the center of the top wall l2 the said chamber 11.

The operation of my device is as follows.

rlie burner is placed in the hre box of a stove with the plug 13 and outwardly projecting portion 15 of the burner conduit resting in suitable bearings. Fuel oil is introduced through the 'fuel supply pi Je l() either by gravity or 4under pressure. tter a Small quantity oi' oil has accumulated in the bowl ot the concave top wall 12 same is ignited. rllhe oil within the vaporizing chamber 11 will become gasitied and rise in the burner conduit. ldhen suliicient gasification has taken place the burner is lighted at the combustion aperture 20.

The flame from the combustion aperture will furnish enough heatwhen concentrated by the concave construction of the top wall l2 to effect suiiicient gasification of the oil within the chamber ll to supply the burner conduit with a continual supply of vaporized fuel.

By experimental knowledge the burner conduit is offset and at sumcient distance away from the vaporizing chamber 11 to prevent said conduit from becoming overheated and deteriorated by the radiation of heat from the bowl of the concave top wall l2, and, at the same time, is in proper relation with said bowl to insure constant and continual gasification of the iuel in its passage through said burner conduit.

The downwardly disposed portion 18 of the burner conduit serves as a trap to catch residual impurities that tail to Igasify. The said portion may be readily cleaned by removing the cap 19.

From the foregoing description taken in connection with the accompanying drawings, the advantages of the construction and of the method of operation of my oil burner will be readily apparent to those skilled in the art to which the invention relates, and while l haveV described the principle of operation of the invention, together with the device which l now consider to be the best embodiment thereof, l desire to have itv understood that the device shown is merely illustrative and that such changes may be made when desired as'are within the scope of the invention.

What l claim is An oil burner comprisinga vaporizing chamber, the said chamber having a concave recess formed in the outer top Wall thereof, a 'fuel supply pipe communicatingwith the said chamber, a plug threadedly disposed in the side wall of the said chamber, a burner conduit threadedly disposed in the side wall of the said chamber diametrcally opposite YLesage@ the said plug, the said plug and the lower end of the said 'burner conduit being cooperatively adapted to serve as supports for the said oil burner, the said burner conduit comprising an outwardly extending portion, an upwardly extending` portion, a diametrically horizontal portion, and a downwardly disposed portion, all of the said portions being` in a diametrically lcentral plane relative to the said vaporiZing-chamber, the said horizontal portion having a downwardly directed combustion aperture formed on the under side thereof disposed concentrically above the said concave recess and a removable lcap threadedly secured to the outer end of the said burner conduit.

y lu witnesswhereof, l hereunto subscribe my name this 10th day of September, A. D. 1920.

, JOHN RHODES.
